摘要

PPROBLEM TO BE SOLVED: To provide a heavy-duty pneumatic radial tire to reduce the separation trouble generated at the folding part of a carcass ply of the bead part without increasing the weight of the bead, prevent the blow failure and exceptionally improve the bead durability by using a reinforcing rubber composition having excellent creep resistance (permanent deformation) and heat resistance at the bead part. PSOLUTION: The reinforcing rubber composition for tire is used as the reinforcing rubber 14 to be placed between a ply folding part 12a and a rubber chafer 13 positioned outside the ply folding part 12a of a carcass 12, opposite to the upper part of a rim flange 40 in the state of the tire attached to a normal rim, and on the outer face of the bead part 10. The composition contains a rubber component composed of natural rubber and polybutadiene rubber and N,N'-diphenylmethane bismaleimide (BMI). The invention further provides a heavy-duty pneumatic radial tire produced by using the reinforcing rubber composition. PCOPYRIGHT: (C)2006,JPO&NCIPI

要解决的问题：提供一种重型充气子午线轮胎，以减少在胎圈部分的胎体帘布层的折叠部分产生的分离麻烦，而不会增加胎圈的重量，防止吹气失败并显着改善通过使用在胎圈部具有优异的耐蠕变性（永久变形）和耐热性的补强橡胶组合物，可以提高胎圈的耐久性。

解决方案：轮胎用补强橡胶组合物用作补强橡胶14，该补强橡胶14置于帘布层折叠部12a与位于胎体12的帘布层折叠部12a的外侧的橡胶胎圈包布13之间。胎圈凸缘40在轮胎的状态下附接至正常轮辋，并且在胎圈部分10的外表面上。该组合物包含由天然橡胶和聚丁二烯橡胶以及N，N'-二苯基甲烷双马来酰亚胺（BMI）组成的橡胶组分。）。本发明进一步提供通过使用增强橡胶组合物生产的重型充气子午线轮胎。
